Patent JP-S6347739-A (JP)
Title: Acoustic-optical device
Inventor: NAKAMURA KENJI
IPC: G02F1/11
Filed: 1986-08-15
Abstract: PURPOSE:To deflect light beams transmitted in a medium within a wide angle range by generating plural electron beams whose intensity is modulated from an electron beam generator while individually controlling them and radiating the electron beams to a medium having an acoustic-optical effect to generate a required ultrasonic wave. CONSTITUTION:In case of deflecting incident light Li by ultrasonic waves APW with high frequency, the wavelength of the ultrasonic waves APW is reduced, so that the incident angle of the incident light Li should be set up to a large value to satisfy Bragg's condition. Namely, the ultrasonic waves APW are generated so as to be transmitted with an inclination to the incident side of the incident light Li from the normal on the surface of a substrate SUB and an angle formed by the wave surface of the ultrasonic waves APW and the incident light Li is set up so as to satisfy Bragg's condition. In case of deflecting light beams by ultrasonic waves with low frequency, the wavelength of the ultrasonic waves APW is increased, so that the incident angle of the incident light Li is reduced to satisfy the Bragg's condition, the ultrasonic waves APW are generated so as to be transmitted with an inclination to the opposite side against the incident side of the incident light Li and an angle formed by the wave surface of the ultrasonic waves APW and the incident light Li is set up so as to satisfy Bragg's condition.
